I never had issues with yours, but i only fitted one of your sets

The problem with the metal extension it was a loose fit on the rear turbo inlet
snout but it fit perfectly on the 1m turbo same measurments you provided

Thats why i didnt bother and ive seen another 1 or 2 set like that since then

I also found that if someone didnt run a bms catch can but had silicone inlets fitted it the breather from the flapper would lubricate the pipe and eventually come off
